PROBLEM TO BE SOLVED: To provide a hydrogen filling device for protecting a PEFC and a hydrogen absorbing alloy from being poisoned by reducing the density of impurities contained in hydrogen. SOLUTION: This hydrogen filling device used for a fuel cell vehicle having a hydrogen filling passage 1 for filling hydrogen to an MH hydrogen tank 7 comprises a bypass passage 2 branched from the hydrogen filling passage 1 to fill hydrogen to the MH hydrogen tank 7, a hydrogen separator 3 having a hydrogen permeable membrane 3b, filling the hydrogen passed through the hydrogen permeable membrane 3b to the MH hydrogen tank 7, and discharging the hydrogen not having passed through the hydrogen permeable membrane 3b which is installed in the bypass passage 2, and a selector means 6 for selectively switching a flow passage for hydrogen led into the hydrogen filling passage 1 to the hydrogen filling passage 1 or the bypass passage 2. |
